High temperature corrosion resistant filter - PP bag filter

High temperature corrosion resistant filter - PP bag filter

As a common equipment for separation of solid and liquid, filter is widely used in pharmaceutical, food, chemical and other industries. In recent years, with the increasingly severe environmental pollution problems, the filter market demand is more vigorous. PP bag filter is a filter system made of PP(polypropylene) material. With the good chemical resistance of PP material, it can meet the filtration application of many chemical acid and base liquids. Aite environmental protection PP bag filter with integrated forming, no welding points, zero leakage and other advantages, has become a popular customer products.

First. The working principle of PP bag filter

The liquid enters from the liquid inlet on the side of the filter and enters into the filter bag above the filter bag supported by the mesh basket. The filter bag expands evenly along the pressure surface due to the impact of the liquid, so that the liquid material is evenly distributed on the inner surface of the whole filter bag. The liquid through the filter bag is discharged from the outlet at the bottom of the filter along the wall of the mesh basket. The filter particle impurities are intercepted in the filter bag to complete the filtration process.

Two, the difference between different PP bag filter

1.PPH series bag filter

1) The connecting flange of the inlet and outlet of the shell adopts the integrated molding design, which is integrated into the fluid conveying system. It is fast to install, simple to support, safe and reliable.

2) The inner surface of the shell is smooth and easy to clean.

3) The basket adopts an integrated molding design, with a handle, in need of cleaning and maintenance, clean convenient and quick.

4) Universal flange, can be used with national standard pipe flange.

2.HTF series bag filter

1) The upper cover can be opened easily by holding both handles.

2) The upper cover can be equipped with pressure gauge and various variable sensors.

3) The protection switch can be installed to monitor the status of the top cover.

4) The upper cover two layer structure design, the inner cover is vertical flat pressure sealing ring, the outer cover will not cause friction and local extrusion of the sealing ring when screwing, so the sealing is very good.

5) There is also a seal design between the outer wall of the top mouth of the net basket and the shell. Under the action of the pressure ring, a 360-degree seal is formed between the filter bag and the shell.

Three, PP bag filter application industry

1. Electronics industry

1) Photochemical polishing, high purity water filtration and pre-filtration as a multi-mode filtration;

2) PCB production process, such as nickel plating, electroplating, timing, development, acid and alkali washing, etc.

2. Metal processing industry

1) Filtration of metal working liquid and filling mixture;

2) Copper/aluminum foil factory, flow process equipment.

3. Chemical industry

1) Catalyst recovery;

2) Filter acid, lye and solvent;

3) Colloid in filter resin.
